Mellotron Looping in Genesis

On the first track of Genesis' album in 1973 called Genesis Live, the group opened up with a Mellotron introduction. The Mellotron is an electro-mechanical keyboard like device that combines together various mechanisms to create different sounds. It is a notable instrument in progressive rock and a lot of bands
turned to using in their songs and work later on. In "Watcher of the Skies", which was the first track of Genesis' album, Foxtrot, they incorporated this very mellotron device.

Watcher of the Skies has an unusual polyrhythm part following the vocals of the song. I personally love how the song picks up after two minutes into listening. It definitely built up suspense and I enjoyed listening to it. It's an odd synchronization of being upbeat with drum and mellotron sounds incorporated into sad vocal lyrics.
